V. M CABE SUPPORTING BASE April 26, 1938.

Filed Dec. 6, 1935 Patented Apr. 26, 1938 UNITED STATES PATENT, oF ic ESUPPORTING'BASE Viola McCabe, Miami, Fla. I Application December 6,1$l35, Serial No. 53,184 I 3 Claims. i (01. us -194) One of the objectsof my invention is the provision of a portable supporting base which maybe used as a weighted base or as a clampingbase,

Another object of the invention is the provision of a base which iscompact, which requires a minimum of space while in use,-and which. iseasily and quickly converted from one type of base to the other. I

A further object of the invention is the provision of. a base having armmembers for adjust ably supporting a magnifying glass, electric lightsocket and bulb, or other like article;

Still another object of the invention is the provision of a new articleof manufacture which is simple of construction, which is economical tomanufacture, and which may be sold to the public ata nominal cost.

Other objects and advantages of my invention will suggest themselves inthe course of the following description, and that which 'is new will becorrelated'in the appended claims.

The most satisfactory manner of carrying out the principles of myinvention in a practical, economical, comprehensive, and efiicientmanner is shown in the accompanying one sheet of draw,- ings, in which:1

Figure 1 is a side elevation of the invention, the same illustrating itsuse as .a weighted base.

Figure 2 is a plan view of the invention, taken from line 2-.2 of Figure1.

Figure 3 is a front elevation of the base, taken from line 33 of Figure1.

Figure 4 is a side elevation of the base, the same being used as a.clamping base in connection with a solid-top table or the like.

Figure 5 is a side elevation of the base indicating the same inconnection with a table or other similar support having downwardlyextending flanges therearound.

Figure 6 is an isometric detail view'of the main body member of thebase.

Figure 7 is an isometric detail view of the clamping member of the base.

Figure 8 is an isometric View of the base in partially assembledcondition.

Similar indices designate like parts throughout the several views.

In order that the construction and the advantages of my invention may bemore fully understood and appreciated, I will now take up a detaileddescription thereof, in which I will set forth the same as fully and ascomprehensively as I may.

A designates a table or other supporting surface upon which the base isadapted to rest.

2, as shownin Figure 8.

designates the mainbodymember, the same being preferablyformed of metal,or of other suit able material. I designates the inverted -L- shapednotch or groove-which is formed in the rear side of: the mainbody'memberl and extends, the fulllengththereof, the same extends forwardly andthence: downwardly, and forms a space for a companion portion of .theclamping member 2. l designates'arearwardly extending channel which isformed the full length of the frontside and; extends rearwardlytherefrom andforming a space for the reception of the hinged member 4.I? designates a comparatively smaller and upwardly extending channelformed in the upper surface of the channel the same being formed thefulllength of the main body member I and provides a space for the receptionof the hinge member 3 of the clamping member 2 designates the mainportion of the clamp- 0 ing member, the same forming a surface'uponwhich the base rests when the same is assembled as" shown in Figures' l,2, and 3. The main portion 2 hasthe upwardly extending leg 2 formedintegrally therewith and at the rear edge thereof with the upwardlyextending portion 2', terminatingjn a forwardly extending portion 2 andwhich is adapted to slide endwise into the upper portion-of the invertedL-shaped groove I of the mai body'member, I, as shown in Figure)? Themain portion 2 also has the leg 2 formed integrally with the forwardedge thereof, the same being formed at right angles to the main portion2 and extends upwardly therefrom. The hinge member 3 extends the fulllength of the portion 2 and has one leaf thereof rigidly secured theretoin any well-known manner. 4 designates the spacing block which isrigidly se cured to the free leaf of the hinge 3 in any wellknownmanner. The spacing block 4 extends 40 the full length of the member 2,as shown in Figure 7. The upwardly extending leg 2 has the raisedportion 2 formed integrally with the front face thereof, the same havinga threaded aperture formed therethrough for the reception of thethreaded screw 5 which is adapted to bear, at its inner end, against thespacing block 4.

6 designates the upwardly extending arm which is formed integrally, atits lower end, with the upper portion of the main body member I, thesame having an aperture formed through its upper end for the receptionof the threaded tension screw 7. 8 designates a second arm member whichis adjustably secured, at its lower end, to

the upper end of the arm member 6 by means of p her I; as shown inFigure'B, withtheupwardlg extending leg 2" and the forwardlyjextendingportion 2" registeringiwith the inverted L-shape'd the threadedadjusting provides means members 6 and 8 7 l0 designates a clampingmember which is for adjustably clamping the (adapted to clamp around thehandle portion of V a magnifying glass or the like, the same; having oneend of the adjusting screw ,ll' rigidly secured in one side thereof withthe opposite end thereof being threaded and projectingthrough anaperture "formed. through the upper-end of the arm member 8'with thethreaded nut l2 adv justab-ly securing the same therethrough. l3
